IMPROVEMENT IN SAW-FILING- MACHINES.

The Schedule referred to in these Letters Patent and making part ofthe same.

Io all whom it may concern Be it known that we, GEORGE Z. VANDERSLICE and BELA L. CHURCHILL, of Phillipsburg, in the county of Centre` and State of Pennsylvania, have invented av new" and valuable Improvement in Sawiling Machines; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this speciiication, and tothe letters and figures of reference marked thereon.

Figure l of the drawing is a front view of' our invention.

Figures 2 and 3 are details.

Our invention relates to means for facilitating the work of the saw-tiler, andv consists in the construction and novel arrangement of a vertically-sliding frame, operated by a spring and foot-rest, and so designed that the file attached tothe lower part thereof may be readily operated in any required direction.

Also, in the adaptation to the frame of suitable scales, -whereby the proper measurements may be effected while the operation of tiling is in progress, to produce in the teeth uniformity ot' bevel and size.

The letter A ofthe drawing represents the slide, arranged to move vertically in a suitable frame, B.

G represents a bar pivoted centrally to the bottom of the slide A, in such a manner that it will have a horizontal motion of rotation about the pivot. l

D is a bar pivoted to the side of the horizontal bar C, and centrally in such a manner `that it may have a free motion of rotation in a Vertical plane.

Secured to this-bar D is the guide-rod E, upon which slides the frame F which holds the tile.

The frame F is held together by the rods a a, which are provided with screwthreads and nuts, whereby the length of the frame is adjusted to snit tiles of differentV lengths.

G G are the handles, arranged to rotate freely in the tile-holder.

Then-the file is mounted the. tang is secured into a suitable socket in one holder, While the point thereof is fixed in the other.

The horizontally-rotating bar C. is designed to permit any desired horizontal angular position to be given to t-he file.

In order to secure uniformity in tilingthe different teeth', a scale, n, is marked on the sliding frame A, thereby enablingthe operator to be precise and exact in his work.

For a similar reason the vertical scale z is gradnated on the end of the bar C, enabling the operator to secure uniformity in the vertical angle.

H represents a foot-rest or stirrup, secured to the frame A, and designed to. enable the operator to draw it down at will.

A spring, K, is arranged to operate in the contrary direction, and draws the entire frame upward when released from the pressure of the foot. y'

This arrangement enables the operator to bring thelile to any -height desired on the teeth, and whenv the tile is not in use, the action of the spring will'draw it up out of the way.

- What we claim as our invention, and desire to secure by Letters Patent, is-

The vertical sliding frame A, when arranged to support the extensible and horizontally and vertically adjustable tile-carrienF, and operated by the combined. action of the stirrup H and spring K, substantially as herein shown and described. l

In testimony that we claim the above, we have hereunto subscribed our names in the presence of two witnesses.
